I’m trying to use the pHAT DAC and the PaPiRus e-ink display on my Raspberry Pi Zero W, but they’re both using pin 18 for different purposes. Playing sound doesn’t seem to mess up the display, but updating the display kills the sound until I reboot (even if I’m not playing something).

Is the pHAT DAC getting confused by the PaPiRus’ signal and shutting down? Is there a way I can reboot it without powering it/the RasPi off? Or are there any other suggestions as to what I might try? I don’t need to play sound and update the display simultaneously.
